Subject: [PATCH] server/Makefile.in: handle separate
 APR_INCLUDE_DIR/APU_INCLUDE_DIR

If APR_INCLUDEDIR and APU_INCLUDEDIR point to different directories,
but for example APU_INCLUDEDIR contains both the apr headers and apu
headers, the "export_files" file will contain duplicate header files,
causing the exports.c file to contain duplicate definitions, making
the build fail.

This commit fixes that by making sure we only use the apr headers from
APR_INCLUDEDIR and the apu headers from the APU_INCLUDEDIR.
